Martinez earned a save against the Marlins on Wednesday, allowing one run on two hits and one walk while striking out four batters over 1.2 innings.

Martinez was called upon in the eighth inning with the Diamondbacks clinging to a one-run lead and the tying run on second base with one out. He struck out Xavier Edwards and got Geraldo Perdomo to fly out to escape the threat, then returned in the bottom of the ninth after Arizona put up two runs in the top half of the frame. Martinez made things interesting by surrendering a run and allowing the tying run to get to second base on a two-out wild pitch, but the rookie closer ultimately slammed the door with a game-ending strikeout. He's notched a save on consecutive days for the first time in his big-league career and remains the team's top option for save chances with Paul Sewald at least temporarily moved out of the closer role.

Miller (3-4) allowed three runs on a hit and two walks while striking out one over two-thirds of an inning to take the loss Wednesday versus the White Sox.

Miller loaded the bases in the top of the ninth inning, and Spencer Bivens allowed all three of those runners to score. That left Miller with his first loss since July 22. The southpaw has allowed eight runs over 12 innings since the All-Star break, adding an 18:10 K:BB in that span. He's now at a 3.93 ERA, 1.27 WHIP and 66:32 K:BB with 12 holds and three blown saves over 55 innings this season. He's earned just one hold since the start of July, so he's not currently in the mix for steady high-leverage chances.

Megill (0-3) took the extra-inning loss Wednesday versus the Cardinals, allowing four runs (three earned) on a hit and two walks over two-thirds of an inning.

Megill got the last out of the ninth inning, but he loaded the bases with one out in the 10th and Nolan Arenado cashed in for a walk-off grand slam. This was Megill's first appearance since July 23 after he missed four weeks with a back injury. The right-hander has a 3.15 ERA, 1.11 WHIP and 40:10 K:BB over 34.1 innings this season. He added 20 saves, two blown saves and three holds while functioning as the closer in the first half, but Devin Williams is in that role now, so Megill will likely fill a setup role.

Williams allowed two runs on one hit, three walks and a hit batsman while striking out two over two-thirds of an inning to take a blown save in Wednesday's 10-6 extra-inning loss to the Cardinals.

Williams was shaky in earning a save Tuesday, and he was even worse Wednesday. He threw just 12 of his 31 pitches for strikes, and two of his three walks came with the bases loaded. Trevor Megill was able to escape the ninth inning with a groundout, but he would up surrendering a walk-off grand slam in the 10th to complete the Brewers' collapse. Williams is now at a 3.12 ERA, 1.27 WHIP and 16:5 K:BB through 8.2 innings this season while converting five of his six save opportunities.

Helsley (5-4) struck out two and didn't put a runner on base in a scoreless inning to earn the extra-inning win over the Brewers on Wednesday.

Helsley had two strikeouts and a groundout to strand the initial runner at third base in the top of the 10th inning, and the Cardinals rallied for a walk-off win on Nolan Arenado's grand slam in the bottom of the frame. This was Helsley's fourth consecutive scoreless appearance after he allowed four runs over 2.2 innings to begin August. For the season, the St. Louis closer has a 2.56 ERA, 1.22 WHIP and 60:22 K:BB while converting 38 of 41 save chances across 52.2 innings.

Estevez allowed a hit and a walk in a scoreless inning to earn the save in Wednesday's 3-2 win over Atlanta.

Estevez is up to 22 saves on the year, but he's earned just two of them since he was traded from the Angels to the Phillies. He's added a 2.47 ERA, 0.85 WHIP and 42:8 K:BB through 43.2 innings this season. Estevez appears to have the edge over Jeff Hoffman and Jose Alvarado for save chances, as neither of those relievers has logged a save in August, though Philadelphia hasn't generated many opportunities this month.

The Pirates outrighted Ryan to Triple-A Indianapolis on Wednesday.

Pittsburgh designated Ryan for assignment Monday, but he'll stick around in the organization after going unclaimed off waivers. Ryan has posted a 5.66 ERA across 20.2 innings over his 15 appearances out of the Pirates' bullpen this season.

The Dodgers reinstated Treinen (hip) from the 15-day injured list Wednesday.

Treinen landed on the injured list Aug. 5 due to left hip discomfort, and he'll now rejoin the Dodgers' bullpen after throwing one rehab inning at Double-A Tulsa, during which he struck out all three batters he faced. The 36-year-old righty owns a 2.67 ERA and 1.09 WHIP through 30.1 frames on the year while working primarily in high-leverage situations. In a corresponding move, Ben Casparius was optioned to Triple-A Oklahoma City.

Tarnok (lat) struck out three and gave up three runs on two hits and one walk over an inning of relief for Triple-A Lehigh Valley on Tuesday after being activated from the 7-day injured list.

The 25-year-old made his first appearance for Lehigh Valley since July 2 after he completed his recovery from a right lat strain. Before being activated, Tarnok made a pair of rehab appearances for High-A Jersey Shore, striking out two over three scoreless innings.

Bednar (3-6) took the loss Wednesday against the Rangers, allowing a run on three hits over two-thirds of an inning. He struck out one.

With the game scoreless in the bottom of the ninth, Bednar allowed a pair of singles to lead off the frame. He managed to retire Nathaniel Lowe and Josh Jung before giving up a two-out, walk-off single to Wyatt Langford. It's the third loss in six outings for Bednar, who's allowed nine earned runs in his last nine innings. His ERA is up to 5.68 on the season with a 1.35 WHIP and 48:15 K:BB across 44.1 innings. Bednar has 22 saves in 27 chances this year, though he could lose work in the ninth to Aroldis Chapman if his struggles continue.
